Hal had reverted his eyes to how they were before his creation of Infinity (Blue irises and white sclera) and that took away his infinite pull but was the only change to his appearance.
His black hair retained its nightmarish hue and while his cultivation remained hidden, he was now constantly exuding authority that he could/did not want to stop.
The journey to the Rose Petal Hotel was fairly quick with the use of a commercial carriage and once he arrived, he made his way in with no one trying to bar his way or asking for credentials to prove that he was authorized to be there.
They all just let him move as he pleased and soon, he was giving a rapt knock to Tanya's office and only entered when he heard the granted permission from behind the door.
No guards were guarding the office and in all honesty, that was not needed.
